brother, tamerlan, killed in a gun battle early friday morning while wearing explosives strapped to his chest, may have instigated the plot and persuaded dzhokhar to join him, but why? the brothers originally from chechnya, were raised in the u.s., living in the same house, and seemed to fit in. both were athletic. dzhokhar, a wrestler, and tamerlan, a boxer. who hoped to be on the u.s. olympic team. but in recent years, tamerlan had changed and became radicalized, according to his uncle, who says he then spoke to a family friend. >> he said there is someone who brainwashed him, some newly convert to islam. >> reporter: in 2011, russian intelligence, concerned about the threat of chech knowian terrorism asked the fbi to investigate tamerlan, based on information that he was a follower of radical islam and that he had changed drastically since 2010, according to an fbi statement. the fbi says a checked databases, interviewed tamerlan and family members, but quote did not find any terrorism activity, domestic or foreign. the fbi says it asked the russians for more, but never got answers.

about thursday night's car jacking. the fbi says surveillance pictures show dzhokhar and tamerlan tsarnaev at a gas station in cambridge where they drove with the owner of the suv they carjacked. one of them, investigators say, began the carjacking by pointing a gun at the driver and saying, "did you hear about the boston explosion? i did that." the carjacker showed the driver he had bullets in the gun and said, i'm serious. at the scene of the shootout in watertown where tamerlan tsarnaev was killed other explosives were also found. in an interview for "dateline nbc," the boston police commissioner said that's one reason he thinks the brothers planned other attacks. >> we had to step over unexploded devices they threw at the officers. i can only understand from that that they had other targets. they were going other places. >> reporter: both charges today carry the death penalty as a maximum sentence. it is a long way before the justice department decides to seek it. if it did, he would be, by far, the youngest defendant in a federal death penalty case in modern times. brian? >>
